编译脚本分析

• build/core/java.mk
  • 配置基础编译依赖包
    • 根据 LOCAL_NO_STANDARD_LIBRARIES, LOCAL_SDK_VERSION, proto等上下文添加依赖包.
    • 标准SDK, 需要添加 core core-junit ext framework

  • 标准中间模块添加

      LOCAL_INTERMEDIATE_TARGETS += \
          $(full_classes_compiled_jar) \
          $(full_classes_jarjar_jar) \
          $(full_classes_emma_jar) \
          $(full_classes_jar) \
          $(full_classes_proguard_jar) \
          $(built_dex_intermediate) \
          $(built_dex) \
          $(full_classes_stubs_jar)
    

  • 可能的中间模块

    • RenderScript/FilterScript to .java/.bc
  • build/core/base_rules.mk
  • 具体中间文件生成规则
    • create common directories
    • full_classes_compiled_jar: java -> classes -> compiled-jar
    • full_classes_jarjar_jar: acp/jarjar compiled-jar -> jarjar-jar
    • full_classes_emma_jar: acp/emmajar jarjar-jar -> emma-jar
    • full_classes_jar: acp emma-jar -> classses-jar
    • full_classes_proguard_jar: acp/proguard classes-jar -> proguard-jar
    • built_dex_intermediate: dx proguard-jar -> dex-in
    • built_dex: acp dex-in -> dex

关键上下文接入点

Input

• LOCAL_BUILT_MODULE_STEM
• LOCAL_JAVA_LIBRARIES

Output

• LOCAL_INTERMEDIATE_TARGETS

整体依赖关系

   make all_modules
all\_modules : $(ALL_MODULES)
ALL\_MODULES += $(LOCAL_MODULE)
$(LOCAL_MODULE): $(LOCAL_BUILT_MODULE) $(LOCAL_INSTALLED_MODULE)
$(LOCAL_INSTALLED_MODULE): $(LOCAL_BUILT_MODULE)

LOCAL_BUILT_MODULE := $(built_module_path)/$(LOCAL_BUILT_MODULE_STEM)
.......

通过让 LOCAL_BUILT_MODULE 产生对具体上下模块的依赖.

例如:

• package.mk

    $(LOCAL_BUILT_MODULE): $(built_dex)
    $(LOCAL_BUILT_MODULE): $(R_file_stamp)
